Ohio coverage starts with BWC
Ohio uses BWC state-fund workers’ compensation, with an approved self-insurance alternative. Start with BWC to confirm the coverage route for your business. Private general liability, property and auto policies do not substitute for Ohio state-fund coverage.
Use the official employer lookup to check recorded coverage status. BWC notes that status can change, so verify it when needed rather than relying on an old screenshot or certificate. Confirm your policy status and required actions directly with BWC.
Know what a base-rate calculation measures
Ohio publishes private-employer base rates per $100 of payroll. The current loaded schedule applies to July 1, 2026 through June 30, 2027. For each confirmed class, dividing payroll by 100 and multiplying by its published rate gives a base-rate calculation.
That arithmetic is useful for checking inputs, but it is not the complete BWC premium determination. Your BWC notice includes payroll, class rates, the applied experience modification and estimated premium. Rating programs and other employer-specific adjustments can change the outcome. Use BWC’s notice for payment decisions.
Compare estimates with actual payroll
Ohio’s payroll reporting and reconciliation process compares estimated payroll with actual payroll after the policy year. Build your budget from a documented staffing plan, then review it when hiring, compensation or operations change. Check the current BWC instructions for deadlines and reportable remuneration.
Before running a calculation, separate Ohio payroll from payroll for work elsewhere and confirm the policy year. For construction, owners or officers, ask about any applicable reporting limits or rules. An accurate hourly wage total is not enough if the payroll treatment is wrong.
Review employers liability separately
BWC state-fund coverage does not include employers liability. Ask an insurance agent about stop-gap coverage for that exposure. Review the actual form and exclusions rather than assuming a general liability policy already supplies it.
A broader review can also address your customer liability, vehicles and property. Keep these private coverages separate from the BWC estimate so you can see which policy responds to which risk and avoid treating a combined number as a quote.
Before you request quotes
Prepare for an agent review
- Confirm BWC coverage status and the policy year.
- Retrieve your assigned class codes and premium notice.
- Gather reportable Ohio payroll by confirmed class.
- Verify the Ohio experience modifier before applying one.
- Ask about owner, officer, construction and multi-state payroll treatment.
- Review stop-gap employers liability with an insurance agent.
Your request is saved for review. Quote timing and agent availability are confirmed separately.
Common questions
Is this a workers’ comp settlement guide?
No. These pages concern employer coverage and premium budgeting. An injured worker should use BWC’s claim resources for benefits and claim-specific questions.
Why might the calculator differ from my BWC notice?
BWC applies employer-specific rating and payroll rules that a simplified estimate may not model. Check the calculator’s assumptions and compare its inputs with your actual BWC notice.
Can I choose the class with the lowest rate?
No. A rate table is not a menu of interchangeable classifications. Confirm the proper class assignment and payroll allocation with BWC before calculating a cost.
